I sourced an old tube radio from an good will store. Since it was defective I got it for free. Anyways, I have already striped the electronics inside so this does not matter. I am going to build a Bluetooth speaker box with the case. Bluetooth receiver, Class-D Amplifier, bass reflex loudspeaker, lead-battery, USB-charging port and a carry handle.

A few years ago I bought this interesting piece of medical equipment history. It is an induction coil with interchangeable gas filled glass electrodes. It was used “treat” all kinds of medical conditions. The handbook shows a large variety of uses this device could be used on, against and for. There are electrodes for your hair, eyeballs, vaginal electrodes and many even weirder ones. All the electrodes from the handbook are pictured at the end of the video.
I think it is a medical quack.
Nevertheless it is fun to show this thing at parties an zap people whit it.

I have the handbook scanned somewhere and will add it to this post any time soon. In the meantime here is a video of me presenting this thing.
